Living Story Achievements after next patch
I am assuming you are talking about the Edge of the Mists tab in the achievement panel? (Since the other three achievements doesn’t really have much to do with Edge of the Mists).
Those are permanent.
Krall Bloodsword – Mesmer
Krall Peterson – Warrior
Piken Square
Krall Peterson – Warrior
Piken Square
The Edge of the Mists section, the one that only has 3 achievements, under the Living World category, will be removed with the patch.
The Edge of the Mists under WvW is permanent.
